<br>
Although I didn't get the time to test it but I had a look at the patch,<br>
<br>
Going by a dry run on the patch it looks to me that it is for creating vendor
defined child devices on "IBA".<br>
<br>
It looks ok to me, I will do a test on it and will reply.<br>
<br>
<br>
We need multiple IOC device interfaces (more than one child device mapping to
same IOC).<br>
If we go on the similar lines, it seems to me that we need to put the same
device creation logic in "ibiou" driver.<br>
<br>
But as specified above by Fab, If we are removing the IOC PnP Manager code from
IBAL, then there will be changes<br>
required in "ibiou" driver because currently "ibiou"
registers a PnP callback for IOC events. <br>
<br>
If IOC PnP manager code is removed from IBAL then we will need SA queries to be
done specifically from "ibiou" driver.<br>
<br>
I want to implement child device creations from "ibiou" too.<br>
Should I remove IOC PnP callback mechanisms in "ibiou" and make it
dependent on user configurations for creating the child devices?<br>
<br>
I am new to IBAL's code, So please let me know if I am getting anything wrong.<br>

<br>
Do you we any updates on "vendor defined device in ibbus"?<br>
<br>
I wanted to create multiple vnic interfaces irrespective of number of reachable
IOCs.<br>
<br>
Currently I am creating vnic child devices on "root" bus.<br>
Inside VNIC driver, I am looking for arrival GUID_IB_AL_INTERFACE and hence
contacting the IBAL.<br>
But since vnic devices are root enumerated, VNIC driver gets loaded very
earlier in boot phase (Before "Extended Base" group to which IB Stack
drivers belong) and hence VNIC device interfaces are not getting initialized
properly.<br>
<br>
If we are providing a vendor defined device functionality in ibbus in near
future, then it would be worth for me to wait for it.<br>
<br>
Can any one please comment on this.<br>
<br>

I came across one more question in my mind which are I think is not clear to me
after reading the whole thread.<br>
<br>
In new design being discussed:- <br>
Are we making sure that we can have more than one child devices configured for
the same IOC.<br>
Currently, there is one child device created per IOC discovered.<br>
<br>
Having more than one child device configured for same IOC is a requirement if a
user wants two different ULP interfaces to be created on host side.<br>
Consider a case in which a host is connected to a single IOC and IOC is
connected to a ethernet network via switch.<br>
If there are two different IP subnets then there is a requirement of two
different Ethernet interfaces on the host side too.<br>
<br>
Please let me know if you need more clarification of my question.<br>

<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'>This
would be done via LBFO for network devices, and MPIO for storage devices.
I think having the bus driver report a single IOC that really maps to two
IOCs on the fabric is asking for management problems. Further, LBFO/MPIO
can provide failover between different device types, so the failover devices
don't have to be identical HW.<o:p></o:p></span></font></p>

<div>
<p><font size=3 face="Times New Roman"><span style='font-size:12.0pt'><br>
I don't know about how MPIO works. But for LBFO, BundleID param will have
to be included in extended params then so that user gets the freedom of
bundling different failover configurations.<br>
